Description
Technical field
The utility model belongs to Forging Technology technology, and in particular to a kind of to improve the concordant supporting bridge set of cylindrical forged piece oral area
Pipe composite extrusion die.
Background technology
In the prior art, casing is stamping forming by the punch and molding die of hydraulic press, specific to produce
Technique is：It after material temperature reaches the forging temperature of central siphon, is then placed in the one-time-shaped mould of hydraulic press, and utilizes oil
Punch of press carries out blank to be stamped and formed out one-pass molding part；Again by the secondary punch on the second hydraulic press to one-pass molding
Part carries out punching press, forms post forming part；Finally post forming part is rushed using the punch three times on third platform hydraulic press
Pressure is to form molded part three times.As moulding process three times.
It is connect for the small molded cannula used on current supporting bridge, according to existing mold, production blank allowance is big, both wastes
Raw material, and increase the difficulty that follow-up machine adds.
In the production of various bobbin shape part blanks, there is different degrees of uneven overlap, and end face in most of blank oral areas
Out-of-flatness not only wastes raw material in this way, but also increases the difficulty that machine in subsequent production adds flat mouth, since oral area is not concordant,
It needs to consider this deformation when designing mold, dimensionally increases surplus.It has to be amputated using sawing machine in following process, Cai Nengbao
The flatness of workpiece size and end face is demonstrate,proved, therefore is taken a lot of work again when existing this design charges, production cost is increased, wastes former material
Material.
Utility model content
To solve defect of the existing technology, the purpose of this utility model is to provide a kind of compact-sized a, machines two
Station realizes the supporting bridge casing composite extrusion die of punching and end face composite molding on a hydraulic press.
To achieve the above object, the technical solution adopted in the utility model：The supporting bridge casing composite extrusion die,
With press ram, there is tablet, tablet there is connection screw thread, connection screw thread to be screwed with for press ram lower part
Extension bar, extension bar lower end connect spiral shell, connect spiral shell and are threadedly coupled Upper Die-sleeve, Upper Die-sleeve has inner cavity, and the lower part of inner cavity is pilot hole, interior
The end of chamber, which has, squeezes the molding integer chamber in workpiece upper end, is set with punch in Upper Die-sleeve, the positioning pressure portion of punch is led
To portion and pressing part, the pressing part stretches out Upper Die-sleeve, the pilot hole cooperation of guide part and Upper Die-sleeve, and there is Upper Die-sleeve punch to exist
The space that Upper Die-sleeve slides up and down, the positioning pressure portion of punch have pyramidal structure, and connecing spiral shell end center has and pyramidal structure
The bellmouth of cooperation.
The upper end of the Upper Die-sleeve is equipped with hydraulic oil inlet and entrance, and the hydraulic oil inlet connects hydraulic pressure with entrance
It stands.
Using the advantageous effect of above-mentioned technical proposal：The concordant die mould compound flushing of the raising cylindrical forged piece oral area, is first forged and pressed
The end position of workpiece makes the end face of workpiece first be molded, because workpiece swaging deformation amount is little at this time, the internal force of extrusion compared with
It is small, therefore end face is smooth, then workpiece bottom is squeezed to realize punch forming by punch.Because workpiece end position is first squeezed into
Type, the moulding section intensity is larger, and in subsequent punch extrusion process, working tips are influenced small, therefore end face by subsequent extrusion
It is smooth, dimensionally stable.The design for reducing workpiece extruding allowance amputates redundance without sawing machine, and end face is smooth, and machine adds end face
Workload it is small, improve processing efficiency, reduce production cost, save raw material.
Description of the drawings
Specific embodiment of the utility model is described in further detail below in conjunction with the accompanying drawings.
The structural schematic diagram of Fig. 1 the utility model.
Fig. 2 is the structural schematic diagram of punch.
Specific implementation mode
Supporting bridge casing composite extrusion die as shown in Figure 1, 2 has press ram 7,7 lower part of press ram tool
There are tablet 1, tablet 1 that there is connection screw thread, connection screw thread to be screwed with extension bar 2,2 lower end of extension bar connects spiral shell 3, connects spiral shell threaded connection
Upper Die-sleeve 4, Upper Die-sleeve have inner cavity, and the lower part of inner cavity is pilot hole, and the end of inner cavity has extruding workpiece upper end molding
Integer chamber 6 is set with punch 5, positioning pressure portion 5.1, guide part 5.2 and the pressing part 5.3 of punch, the punching press in Upper Die-sleeve
Upper Die-sleeve is stretched out in portion, and the pilot hole of guide part and Upper Die-sleeve coordinates, and Upper Die-sleeve has punch in the space that Upper Die-sleeve slides up and down,
The positioning pressure portion of punch has pyramidal structure, and connecing spiral shell end center has the bellmouth coordinated with pyramidal structure.The upper mold
The upper end of set is equipped with hydraulic oil inlet and entrance, and the hydraulic oil inlet connects hydraulic station with entrance.
